Altitude Inc., a Boston-based design firm, released the prototype for a laser-projected bike lane to accompany cyclists during night trips. Alex Tee and Evan Grant, the engineers behind the concept, designed the tool to ensure safety for cyclists by making them visible on the dark road.

The tool, appropriately titled, “LightLane,” is a great companion to conventional “blinky” lights, which only light up the center point of a cyclist without defining the dimensions. LightLane displays the image of a bike lane on either side of the cyclist and projects as far back as 10 feet onto the pavement. The device is compatible with universal mobile-phone charger standards and runs on rechargeable lithium-ion batteries, which are known for their slow loss of charge and high energy densities that allow them to pack more energy into their small frames.
